PHOTO-ACTIVATED PRODUCTION OF FREE RADICALS FROM DIATOMIC MOLECULES AFTER ADSORPTION ON METALLIC SURFACES. Annual progress rept., 1 Oct 60-30 Sep 61, by C. M. Moser. 30 Sep 61, 15p. (Contract DA 91-591-EUC-1543) Unclassified report DESCRIPTORS: (*Carbon compounds, *Monoxides, *Nitrogen compounds, *Oxides, Atomic energy levels, Excitation, Hyperfine structure, Electron transitions, *Quantum mechanics, Atomic spectrum, Atomic structure.) (Crystals, *Nuclear magnetic resonance, Programming.) (Free radicals, Production, Photochemistry.) A summary is presented of research on the calculation of ground and excited states of diatomic molecules (CO and NO) and the calculation of the magnetic and electric hyperfine constants of first row atoms. Discussions include: (1) electronic structure of CO; (2) nitric oxide; (3) magnetic hyperfine constant of the N atom; (4) dependence of induction and dispersion energies at finite internuclear distances; and (5) calculation of the magnetic resonance spectra of a system of 2 spins of 1/2 in polycrystalline material.
